TU356L BB Tuba

The new 4 piston valve 3/4 is based on the Yamaha 3/4 103 model with one huge difference, the addition of a 4th valve. Not only did we add the 4th valve but we increased the bore size as well. The TU356 bore for valves 1-3 is a .689 and valve no. 4 is a .707 which allows for a more open lower register. 

With the addition of the 4th valve, this is one of the most versatile small tubas available. Not only is it great for the younger student because of its size but also the adult pro looking for a smaller compact BBb for solo work, chamber, studio, quintet, etc. and everything in between.
